Mineralogically and biologically complete substrate
For planted aquariums
Comes in live water that contains purifying bacteria
Mineralogically complete means it contains iron, calcium, magnesium, potassium, sulfur plus over 25 other elements to nourish your aquatic plants. It contains all the mineral nutrients needed for luxuriant aquatic plant growth without nuisance algae. This iron-rich substrate eliminates the need for laterite.Biologically complete means it contains live heterotrophic bacteria to rapidly convert fish waste into natural food for your aquatic plants; creates a natural biological balance which makes cycling a new aquarium faster and safer; packed in Liquid Amazon buffered "Black Water" solution for immediate organic water conditioning; unsurpassed MacroPorosity for healthy roots and bacterial efficiency. You would need to buy 4 bags of ordinary gravel to equal the surface area of this one bag of substrate.Other features include: nitrate and carbonate free-will not increase pH or carbonate hardness; there are no artificial dyes, paints or chemical coatings; the natural black substrate encourages the most vibrant coloration in fishes and reduces fish stress; spherial grains for optimum diffusion performance; supplies calcium without raising the pH; lead free.The Bi-Modal grading naturally separates into 2 distinct layers: 1) Fine layer on the bottom for best root development and 2) Coarse layer on top which conveys oxygen and nutrients to the roots.Instructions:Use 1-2 pounds per gallon of aquarium water. Two pounds or more per gallon will deliver best performance. An ideal depth is at least 3".It is designed to be a complete substate but may also serve as a bottom layer with your choice of non-carbonate substrate on top (do not use marble, dolomite, limestone, crushed coral, shells aragonite etc.).For new aquarium set-ups simply pour in the entire contents of this bag and fill aquarium with de-chlorintated tap water or, for best results, de-ionized or distilled water. It will automatically segregate into 2 distinct layers with the finer material on the bottom.For established systems, drain and discard most of the liquid contents of the product before placing into the system.Warning!!! Placing new gravel over the top ("capping") of an estabished gravel bed can be damaging to aquatic life. Gently mix new material into the existing bed with fingers. For added safety this process can be done, in sections, over the course of a few days.Place aquatic plants with roots deep into the substrate. Plants may be held in place with the aid of small rocks, pieces of wood, etc.

Specifically designed to be used in deep sand beds
Effective denitrifier
Safe for sifters and soft bellied fish
Directions: General Use: For best results, use at least 1 pound of AragAlive! per gallon of seawater. For deep sand beds use 2 pounds per gallon. Do not rinse. AragAlive!™ may also be used to seed CaribSea’s dry aragonite products. AragAlive!™ compresses new tank cycle time and suppresses initial ammonia spike. Live rocks and most invertebrates may be placed in aquarium immediately. However, gradually introduce fish within the first 3 weeks, and do not exceed one inch of fish per gallons of water during this time.
Berlin Systems: The most suitable substrates are AragAlive!™ Fiji Pink (#00792), AragAlive! West Caribbean Reef (#00794), AragAlive!™ Bahamas Oolite (#00793), or AragAlive!™ Indo-Pacific Black (#00791). Use 1 pound per gallon. Place live rock on top covering the least amount of sand as possible. Use small reef friendly hermit crabs, shrimp, serpent stars, sea cucumbers, and other benthic animals to avoid detritus accumulations.
Sumps, Refugiums, and Deep Nitrate Reduction Beds (DRN): For offline systems, such as sumps and binary systems, the deepest bed possible is suggested for the non-display unite. Use AragAlive!™ Florida Crushed Coral (#00795) or AragAlive!™ Special Grade Reef Sand (#00790) and/or corresponding CaribSea Dry Aragonite. Plant macro-algaes such as Caluerpa sp. and illuminate on a counter daylight cycle to the display tank, or for 24 hours. When illuminated, these macro-algaes help control pH by absorbing carbon dioxide while releasing surplus oxygen. They also help control nuisance algae in the display aquarium by absorbing excess nutrients. These type sumps and binary systems are especially effective in maintaining good water chemistry in display aquariums larger then 75 gallons.
For Deep Nitrate Reduction Beds in Display Aquariums use AragAlive! Special Grade Reef Sand (00790), AragAlive! Fiji Pink (#00792), AragAlive! West Caribbean Reef (#00794), AragAlive! Bahamas Oolite (#00793), or AragAlive! Indo-Pacific Black (#00791). Add substrate to a depth of 3 to 5 inches (2 to 3 pounds per gallon). Place base or live rock so as to cover the least amount of the substrate as possible. It is especially desirable to incorporate burrowing and sand sifting fish and invertebrates for optimum health of these systems.
Stingrays, Sharks, and other soft-bellied bottom dwellers: Use AragAlive! Bahamas Oolite (00793) at one pound per gallon or more. Due to the natural sphericity of the individual grains, oolite is favored by public aquariums and research institutions for use in their systems harboring rays, skates, sharks, and other bottom dwelling fish and invertebrates.
Warning! Placing new substrates over the top of an established substrate bed can be damaging to aquatic life. Gently mix new material into the existing bed with fingers. For added safety, this process can be done in sections, over the course of a few days.
